, To aZZ whom t may concer/n Be it known that ll, GEORGE L MAsoN, acitizen of the United States, and resident of Warehouse Point, county ofHartford, State of Connecticut, have invented certain new and usefulImprovements in Serving Spindles, of which the following is aspecification.

This invention relates generally to serving spindles or heads forwinding or wrapping one strand about a second strand or core of the sameor a different material; for instance,- a metal ribbon about a strand ofcotton or other pliable fabrc.

The object of the invention is to provide a device of this sort which iseflicient and reliable in operation, and particularly in that thecovering strand or metal ribbon is uniformly and evenly wound about thecore.

ln the accompanying drawing, l have illustrated my improvements appliedto a serving spindle such as is illustrated and described in application`Serial No. 331,816, filed by myself and George M. Montgomery, but it isevident that my improvements may be used on servingspindles of othertypes. lt is to be understood that the present invention is by way ofillustration only and that the construction may be variously modifiedwithout departing from the spirit of the invention.

lin said drawing:

Fig. l is an elevational view ofthe serving spindle, a portion thereofin longitudinalsection, and

Fig. 2 is an enlarged sectional view of the torward endof the device.

Before describing the improvements of the present invention, the generalarrangement of the serving spindle here selected for illustrativepurposes, and the particular structure of which forms no part of thepresent invention, will be described. a.' isa spool containing thecovering strand or metal ribbon and carried by a sleeve 5 surroundingand in frictional engagement with, so as to be rotated by, a spindle 0journalled on astationary tubular member d through which is drawn thecore strand e as by a driven spool s. Extending through this member and'projecting beyond the forward end thereof is a tapering needle f mountedfor longitudinal adjustment. Fixed to the spindle is a flier g having apivoted thread guide h through the eye of which the metal ribbon isthreaded. The forward end of the sleeve b is held in frictionalengagement with a shoulder i by a tensioning device of which the threadguide z. forms a part, as described the said Montgomery & Masonapplicaion.

lt will be understood by those familiar with the art that, in o eration,the flier will lay the .metal ribbon, esignated by the letter c,1n aspiral manner upon the core thread e. 'lfhe object of the needle is tocause the metal rlbbon to be wound loosely on'the core, that is, to makethe loops or convolutions of the ribbon of greater diameter than that ofthe core so that the composite thread can be flattened out by passing itthrough rolls,if so desired. By adjusting the needle longitudinally, thediameter of the loops or convolutions of the metal strip may beregulated.

Heretofore, in constructions of this general type, the metal ribbon hasbeen entirely free and unsupported between the thread guide of the :dierand the point at which it 'is wound onto the jcore, with the result thatthe winding point, that is the point at which the metal strip is laid onthe core, varies or moves and frequently this winding point will advanceforwardly beyond the needle. This faulty operation necessitated theconstant attention of an operator, the work turned out vwas uri-uniformand faulty and the device could be operated at only relatively lowspeeds.

Referring now to the improvement of the present invention and with whichthe above and other objections incident to thev past practice areovercome,`the ynumeral 10 denotes, what may be termed for convenience,

a head (most clearly shown in Fig. 2) which small centrallylocatedopening 13 through vwhich the needle f projects and aneccentrically positioned opening 1t through which the core strand e -isthreaded. llf desired, the needle and core may both pass through thecentrally located opening. lltwill be seen that by recessing the head aring like portion .or annulus is provided. The arrangement of the partsis such that the thread guide of the flier is rearwardly of the forwardend of the head l0 so that during the winding operation the metal ribbonis drawn across the shoulder or forward face of the annulus. I havefound that with this arrangement the metal strip, after it engages theannulus, will be directed at substantially right angles to the corestrand and needle and the point at which the metal ribbon is woud on thecore and needle is thereby maintained constant. The results are thedevice operates with great uniformity insuring that the metal strip isevenly and smoothly laid onto the core and the attention of an operatormay be dispensed with except for the purpose of replenishing the spools,and furthermore, the device may be run at much higher speeds than hasheretofore been possible.

I claim as my invention l. In a device of the character described, aflier for laying a covering strand ont-o a core strand, and a stationarybridge between said iiier and the winding point and over which thecovering strand is drawn.

2. In a device of the character described, a needle along which a corestrand is adapted to be drawn, ay flier for winding a covering strand onsaid needle and the core strand, and a bridge having an edge spaced fromsaid needle and over willich edge the covering strand is drawn.

3. In a device of the character described, a flier for laying a coveringstrand onto a core strand, and an annulus through which the core strandis drawn, said annulus supporting said covering strand at a pointbetween said Hier and the winding point.

4. In a device of the character described, a needle along which a corestrand is adapted to be drawn, a flier for laying a covering strand ontothe core strand and said needle, and an annulus encircling the needleand core strand but spaced therefrom and arranged to support thecovering strand at a point between the flier and the winding point.

5.w In a device of the character described, a needle, means for drawinga core strand longitudinally thereof, a flier including a.

thread guide for winding a covering strand on the core strand andneedle, and a ring like member encircling the core st-rand and needleand positioned forwardly of the pla-ne in which said thread guiderotates so that said covering strand will be drawn over the edge of saidmember and deflected thereby toward the core strand.

` 6. In a device of the character described, a member forming a passagefor a core jstrand, a needle extending through said passage, a flierincluding a thread guide and rotatably mounted on said tubular member,and a circular head on the forward end of said member and encirclingsaid needle and core strand, the 'forward end of said head beingrecessed providing an edge positioned forwardly of the thread guide overwhich the covering strand is drawn.
